Jim Hansen, a former NASA scientist and advisor to Al Gore who was the first to put global warming on the public radar in 1988, wasn’t fooled. “It’s a fraud really, a fake,” he said in December. “It’s just worthless words.”

From Ernest Moniz’s written testimony for today’s House hearing on Obama’s climate change plan: 'The third part of the President’s Plan is leading international efforts to address climate change. Although we are still one of the largest emitters on a per person basis, U.S. emissions represent only about a fifth of the global total. As such, a global effort will be required if we are to avoid increasing climate damages in the future.'
